<Oh!
Click> The second search term is 'dolphins suffering from noise pollution'.
Just as people raise their voices when talking in noisy restaurants, research has shown that dolphins also raise their voices in noisy environments.
Researchers from the University of Bristol in the UK put two dolphins in a lake and observed them with and without noise. When the volume of a speaker at the bottom of the lake was increased, the dolphins changed the volume and duration of their sounds to overcome the noise. .

The problem is that the louder the noise, the more often the dolphins fail to communicate.
As noise pollution has increased rapidly over the past decades due to increased human marine activities such as ship navigation, oil drilling, and wind power generation, abnormal behaviors of marine organisms such as whales are also increasing. It is an evaluation that it is a research result that supports the fact that it interferes with hunting and mating.

Netizens said, "It's not just that I don't like hearing it, it's affecting survival itself."
"Dolphins who can't even talk and just hang on... I feel guilty."
and so on.
